Regardless of how many times in succession I run Ccleaner, in the Cleaning Complete screen under Details of files deleted, there is a listing for Windows Log Files. Beginning a few days ago, my daily scans show the number of KBs increasing. It never goes away, as it once did. What can I do, besides unchecking System: Windows Log Files, to get rid of it in the Cleaning complete screen? Obviously, Ccleaner isn't doing anything with them Thanks.

You don't say which OS or version of CCleaner you're using, but it's the same issue and devs are aware.
